JNA : About

JNA (Java Native Access) is a Java library published under LGPL which provides Java programs easy access to native shared libraries (RTL, System services on OpenVMS) without writing anything but Java code – no JNI or native code is required.

Philippe Vouters has ported JNA 3.2.7 on OpenVMS. Porting means modifying the source code in order to take account of the OpenVMS specifics, writing some examples of JNA use on OpenVMS and creating a PCSI kit.

JNA for OpenVMS needs Java 1.6.0 or later and libffi 3.0.9 . JNA must be installed on an ODS5 volume and has been tested on Itanium.
